The exhaust manifold 2 isprovided with 1 branches 5, 6,7. and 8 which'a're adapted to be connected to the exhaust ports of the internal combustionengine and through which thefexhaust gasesare adapted to pass to a muffler,- not shown, through-a pipe 9. The exhaust manifold'2 has aqcentral enlargement-'10 to providean outlet passage 11 and an inlet passage 12, said inlet passage commaamti gwith a longitudinally disposed passage '13 whichis in communication with. themain passage 1 10f the exhaust manifoldthrough agt'riangular opening 151for the purpo sehereinafter fully described; From the above descriptionit will be seen that I have V formed an exhaust manifold divided to form passages which are in communication with each other; through afv'alve controlled open- Theintake manifold 3 is provided with a central induction passage 16 terminating at itsnupper end in a chamber 17 from which extend oppositely disposed branches 1 8 and 19 terminating in right angleends 20' and 21 adapted to be connected to the respective in;

take ports of theinternal combustion engine. A central branch 22'extends from the chamber 17 which terminates in nip ples23and24 adapted to be connected to the respective intakes "of the internal combustion engine whereby the explosive charge produced in'the charge forming device'f l is delivered to the respective intake ports of theinternal combustion engine.

The induction passage of the intake manifold iszs'urrounded' by heating chambers 25 and the heating chambers are constructed to and 26 on the opposite sides of the manifold 'conform'to the shapevofthe enlargement of the'exhaust manifold so thatithe exhaust gases will circulate down the heat chamber 26, and up the heat chamber 25 as will be more 7 fullydescribed,thetwo manifolds being connected together by any suitable means, such asbolts and the like,

The'charge forming device is provided'at a vertical section through the ed to register. respectively with the heat chambers 25 and 26' sothat "astheexhaust gases icirculate down through one of the heating chambers of the intake manifold, they 7 sage 1 1 of the exhaust manifoldmIt, jof V cour'se,is understood that the valves, which: i

will be hereinafter fully described, are'in' 'su'chaj position as to allow the'gases to flow in this-manner;

The exhaust throtthngi-valve 29'controls .the passage of exhaust gases through the, main exhaust passage andis preferably the form ofa win'g'valve, one of the wingsbe' ingprovided'with a substantially triangular plate swarming a valve for the opening 15 for controlling the passage of exhaust gases [through the othericexhaust passage of the manifold so that the o'utletin' the heating chamber ofthe intake-manifold will be con-"1 6 trolled through the medium of'this valveas the exhaust throttling valve is opened and closed, the position-of the plate in respect to the wings of the'valve being clearly shown in Figures-5a to 8a in the various positions the valve assumes as it is openedby jthefmovement of the-Vcharge-thr'ottling valve; r V

In order to allow the exhaust throttling valve to dwell on its seat or to remain in closed positionduring a portion of its :move ment, the opposite walls of the passage of.
